SANDING-MACHINE.

Specification of Letters Ifatent.

Patented Aug. 16, 1910.

Application filed December 19, 1908. Serial No. 468,284.

To all whom it may concern:

Be it known that I, ZEPI-IERIN PHILIP OHARPEN TIER, a citizen of theUnited States, and a resident of Auburn, in the county of Androscogginand State of Maine, have invented a new and Improved Sanding-Machine, ofwhich the following is a full, clear, and exact description.

This invention relates to sanding machines for scouring the heels ofboots and shoes, and relates more particularly to a machine of thisclass which comprises a scouring wheel having sand paper or similarmaterial on the surface thereof.

The machine includes means for drawing off the dust resulting from theoperation of the wheel, the means including a reversible hood at thewheel, suitably connected with a blower or similar device.

The object of the invention is to provide a simple, durable andefficient sanding machine for scouring or sanding the heels of boots,shoes and the like, whereby the length of time necessary and the numberof operators requisite, are decreased, and in which the parts can beadjusted so that a righthanded and a left-handed operator can use themachine equally well.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and particularly set forth in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which-- Figure 1 is a frontelevation of an embodiment of my invention; Fig. 2 is a side elevationof the machine; and Fig. 3 is an enlarged cross-section showing a detailof the structure.

Before proceeding to a more detailed explanation of my invention, itshould be clearly understood that while the machine is particularlyuseful for scouring or sanding heels in the manufacture of boots andshoes, it can also be advantageously employed for similar operations fordifferent purposes. The sanding wheel or roll may be of any suitabletype and consist preferably of iron cores having wooden or other rimsupon which are mounted sheets or strips of sand paper, emery cloth orthe like. These and other details of construction can be varied inaccordance with special conditions and individual preference, Withoutdeparting from the spirit of the invention.

Referring more particularly to the drawings, I provide a frame 10consisting of standards or uprights 11 each having a pair of supportinglegs 12. The legs have feet 13 of any suitable form for mounting themachine in place upon a fioor or the ground.

The standards 11 have intermediate the top and the bottom, bearings 26in which is journaled a shaft 27. The latter is a driving shaft and haspulleys 2S and 29, one of which is loose, so that the driving shaft 27can be actuated from any suitable source of power, such as a steamengine, a main shaft actuated by a prime mover, and the like.

The frame intermediate the top and the bottom has a cross member 32 andat the top an arm 33. The member 32 and the arm have bearings 34C inwhich is journaled a shaft 35. The latter is substantially vertical. Itcarries a scouring wheel or roll 36, and at the lower end has a drivenpulley 37, adapted to be connected by a quarter-turn belt 37 with adriving pulley 38 upon the shaft 27. A partly cylindrical hood 39 islocated at the roll and is connected by means of a tube 40 with the pipe20. At one edge the hood has a rail or guard 41. The hood 39 can bereversed or shifted, that is, changed from one side of the roll 36 tothe other to adapt it for use by a left-handed or a righthandedoperator.

The hood 39 may be made reversible in any suitable manner; as shown forexample, herewith, it has a part 39 pivotally mounted by means ofannular hub sections 40 upon a shaft35. The part 39* can be swung fromone side to the other as is indicated in dotted outline in Fig. 3. Ithas at each edge a guard rail 41.

The scouring roll 36 has a fine sand paper surface, and it is ofcomparatively small diameter to serve more efliciently in removingscratches and dents from heels. The heel is pressed against the roll 36in a substantially vertical position. The guard 41 permits the heel tobe steadied against the roll in any desired position and prevents injuryto the uppers of the shoes, and to the hands of the operators.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. In a sanding machine, a substantially vertical shaft adapted to bedriven in either hood encompassing said roll and arranged to bereversed, and a tube for connecting said hood with air exhausting means,said hood 15 having a guard.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
